The Stovebolt Site Forums The Shop Area Engine Shop babbited bearings

I've decided to fully restore my 47 6400 big bolt, that will mean an overhaul on the motor eventually, I know the 47 235 engine had babbited bearings, so being the do it yourselfer I am, if I rebuild my own motor, what do I have to look into. I know I can't do anything with the bearings myself, but does anyone know who can

Talk to EGGE. Think about changing over to insert bearings. www.egge.com

If you crank shaft is still standard size then I have NOS connecting rods standard size.. I also have NOS pistons, rings valves. oil pump water pump and a head ect. E-mail me if interested bwbugay@aol.com

chevy, I'll have to look into it when i get the motor down, I'm just debating what to do at the moment, don't know what to expect when i pull the motor and tear it down, hasn't been run since leaded gas was normal at the pumps, motor is currently locked, I have it soaking with penetrating oil and marvel mystery oil to see if i can get it to even turn, I'll keep you posted.

Unless the bearings are flaking away or the crankshaft is worn out of round, just adjust the clearance and go back together with the same rods. It's possible to do a very precise job of fitting the bearings to the crank, as long as you have some soft metal to work with. I've accumulated sevral sets of undersized reconditioned rods from ebay, including some NOS standard-size military surplus rods still in the cosmoline- - - - -never installed in an engine!

Just get a tube of Prussion Blue and scrape-fit the bearings to the crankshaft, then adjust the oil clearance with the correct thickness of shim.

Edit: Send me the crank and rods, and I can fit and clearance them if you're uncomfortable with trying it yourself. Just be sure to mark which rod goes with which cylinder.

Kissfan, I would stay away from Egge Machine. I had a really bad experience there. They bored the cylinders of my 1936 Chevy pickup engine and instead of keeping it inside the building after the boring work was done, they left it outside in the rain! Yes, that actually happened.

When I confronted them about the mess they made they wanted to hone the block again to remove the rust. I refused that offer because honing is a finish sizing procedure, not a rust removal procedure, and I did not want to start an engine rebuild with out of specification bores.

Fortunately I have a friend in the technical department of one of the big car companies. He researched the subject and found something that would etch out the rust but not attack the unoxidized iron.

Beware of Egge!

Wow. That is sad. You would have thought they would at least have oil wiped the cylinder walls if they were going to leave it outside that long. I guess my rods were small enough to keep inside.
